This patch adds support for global block matrices. A global block matrix
can be obtained by
create_sparsity_pattern(BlockMatrix, dh, ch)
or bycreate_sparsity_pattern(A::BlockMatrix, dh, ch)
. The former infers theblock sizes by looking at the fields of the DofHandler, and the latters
uses the blocksizes of the (partially) initilized BlockMatrix (i.e. by
undef_blocks
).For global assembly,
start_assemble(::BlockMatrix, ...)
returns aBlockAssembler
which pre allocates a vector for pre-computing the(block number, local index) pairs for each DoF. BlockArrays only support
local condensation of constraints currently and you have to use
apply_assemble!
instead ofassemble!
+apply!
